PL HEL what is the end behavior for this function f(x)=x^4+4x^2+2x-4

When x goes to negative infinity, y goes to positive infinity; when x goes to positive infinity, y goes to positive infinity.

Step-by-step explanation:

The largest power of this function is 4, since the term is x^4. This means that the graph of the function will closely resemble a parabola.

Since the coefficient of x^4 is positive, that means that the parabola will resemble a smile.

The end behavior is when x goes to negative infinity, y goes to positive infinity; when x goes to positive infinity, y goes to positive infinity.

Hope this helps!
